The devices we use in space (eg. satellites, probes, or exploration robots) need energy, among other things, to operate, interact with their surroundings, send data, and move. Normally, they obtain this energy from solar panels that convert sunlight into electricity and, in some cases, store it in batteries or other storage systems. This works very well when there is enough sunlight, but not in places where little or no light reaches, such as areas that are always in darkness, like the far side of the Moon.
RepowerSiC proposes another way to deliver energy in space using photovoltaic converters. The idea is to transmit power wirelessly through a laser beam that goes from a source, such as a satellite equipped with solar panels, to a receiver located on the spacecraft or device that needs power. This receiver directly converts the laser light into electricity. This new technology could pave the way for new types of exploration that are currently impossible, such as missions on the far side of the Moon or in deep space.
RePowerSiC supports the Pathfinder Challenge goal of creating efficient, wireless, and secure power transmission in space. It focuses on developing a new laser power converter using silicon carbide (SiC) and innovative device designs. This technology can transfer high power (up to kW/cm²) with excellent efficiency over long distances, while making the receiver smaller and lighter. RePowerSiC is also eco-friendly and cost-effective, using sustainable, non-toxic materials. It enables reliable power for remote space systems, increases payload capacity, reduces the need for batteries, and helps make future deep-space missions possible.
